Safari autofill incorrect name

Safari autofills incorrect name on all my apple devices. iMac , iPhone and iPad.

-After 3 support calls and finally asked to reinstall the OS on Mac.

Safari was autofilling my nickname on all Safari web forms.

All the standard solutions where addressed repeatedly. Apple was stumped.

I gave up and began to use Firefox as browser. no problem there.

Finally I dug deeper into this after looking into "Keyboards on my iPhone, for unrelated issue.

I Noticed "Text Replacement " >

Scrolling down, there was built in OMW, TY, TEH and then there it was, My Nickname was sitting there as a text replacement next to the corresponding Letter.

when I had done that and why I don't recall. So I deleted it and the issue is resolved. WOW.

I praise myself for my diligence and wish to share with others.
